- On a failure the pairing dialog stays open and shows the reason in red (Cancel becomes Close); before, it closed at once and the reason was only in the Server tab's status line. - "Pairing is not enabled" only when the server says so. Any other 404 (a server older than 2.1.0, or a proxy's page) is reported as a server without pairing. - Pairing and Test connection name the problem: a server name that does not resolve (Test connection used to say "No internet connection"), a server that does not answer, or the HTTP status.
